I also use the 0.2 radius for the Hoplite and shieldwall/phalanx like units.

What I did first was to remove the KH of having guard mode all the time in descr ai formations. Then Hoplites fight very well and realistic. Basicly guard mode but then more mobile and stronger.

Also, Ekdromoi and Thureophoroi and Thorakitai I left as normal spear man since individual combat was more important for them I believe?

I strongly advise it for EB(and all other mods) to use it as it really makes the mod better, in looks and historical accuracy and gameplay.
